Step 1 - Check your connections
You'll need to check that your TV box is connected correctly. Make sure the white cable coming out of your TV box is firmly connected.
If your TV box is connected to your hub make sure the white wire going into your hub is also tightly connected. Your hub should also be in the upright position.
